Road gritting and salting in Dorset
Which roads are salted and gritted during winter and the latest gritting updates
During winter, we make daily decisions about when and where to salt based on local forecasts for five distinct climate 'domains', shown on the map below. We will decide whether to salt each domain or the whole salting network.
If you want to know more about our winter road service, read our frequently asked questions.
See when we last treated the main network (red routes) and when we are scheduled to treat them again.
Please note: as we don't routinely treat community links (blue routes) previous and next treatments are not shown for these routes. You can find out when we do, by following us on Twitter @TravelDorset.

Use the map below to see the network of roads we will treat and plough during the winter. Use the Layer Control panel (on the right of the map with the icon of two rectangles) to turn layers on and off, including Ploughing Routes and more.
Guide to the Map
We will treat the main salting network, consisting of 680 miles of roads, when conditions are damp and road temperatures are forecast near freezing or before snow.The A31, A35 (west of Bere Regis) and A303 trunk roads are treated by the Highways Agency.
A network of community links will also be salted when snow is forecast to connect more isolated communities to the main salted network. After snow has fallen we will plough and continue to salt/grit these roads.
During severe snow we may need to fall back to priority ploughing routes to keep the main north-south and east-west roads open.
